Effect of sowing environments and foliar spray of agro-chemicals on quality and biochemical changes of wheat (Triticum aestivum L.)

Abstract

A field experiment was carried out at Instructional Farm, Department of Agronomy, Rajasthan College of Agriculture, MPUAT, Udaipur during rabi 2017-18 and 2018-19 to study the effect of sowing environments and foliar sprat of agro-chemicals. The experiment was laid out in split-plot design with four replications involving four sowing environments viz, D1- 15th November, D2- 30th November, D3- 15th December and D4- 30th December as main plots and five agro-chemicals as sub plots viz, A1- water spray, A2- KCl 0.1%, A3- KCl 0.2%, A4- Salicylic acid 100 ppm and A5- Salicylic acid 200 ppm. Results showed that among different sowing environments, crop sown under 15th November recorded the significantly higher protein content. Among agro-chemicals, foliar spray of salicylic acid 100 ppm recorded the significantly higher protein content over rest of agro-chemicals treatments. 30th December sown registered the highest proline content which was significantly superior over rest of sowing environments. However, foliar sprays of agro-chemicals fail to produce any significant effect on proline content of wheat leaves.
